MICHAEL H. LAN'IZ, OF MARIONVILLE, MISSOURI, ASSIGNOR OF ONE- FOURTH TO NELSON THOMAS OLEVENGER, OF SAME PLACE.

METHOD OF AND DEVICE FOR COALING LOCOMOTIVE-TENDERS WHILE IN MOTION.

SPECIFICATION forming part of Letters Patent no. 276,051, dated April 17, 1883.

Application filed September 12, 1882. (No model.)

To all whom it may concern:

Be it known that I, MICHAEL H. LAN'IZ, a citizen of the United States, residin gat Marionville, in the county of Lawrence and State of Missouri, have invented a new and useful Method of and Device forTaking Coal on Locomotive-Tenders while in Motion, of which the following is a specification, reference being had to the accompanying drawings.

Thisinvention relates to an improved method of and device for taking coal on locomotivetenders while they are in motion, and has for its object to provide simple, inexpensive, and efficient means for accomplishing this result in a safe and ready manner.

In the drawings, Figure l is a perspective view ot' the device in operation. Fig. 2 is an end view of the same out of operation. Fig. 3 is a top view. Fig. 4 is a vertical sectional view on the line 00 00, Fig. 3. Fig. 5 is a side view of the elliptic quadrantal tube. Fig. 6 is a modification thereof.

Referring to the drawings, A designates one of the sides of a locomotive-tender, it being provided at its outer edge with an upright flange, B, on which is hinged the taking-in tube or chute D. Tube D comprises a top, E, bottom F, having preferably a beveled front edge, G, inner curved wall, H, forming a quadrant of a circle, and outer curved wall, 1, forming a quadrant of an ellipse. Top E is provided with a projection, J, which forms a support when the tube is down, and with a pin, K, in its front edge. The side A is provided on its outer face with a vertical bifurcated standard, L, the arms of which, M M, are each formed with a slot, N. On the opposite side is arranged a vertical guide, 0, having a longitudinal slot, P. In standard L is fulcrumed the stem Q of a substantially T lever, B, the operating-arm S of which works in the slot P of guide 0. Stem Q is provided with opposite lateral pins, T T, which work in slots N N. The weight end or arm U of lever B is formed with a slot, V, in which works the pin K. Thus in lowering tube D the arm S is first elevated until its fulcrum moves down in the standard L to its fullest extent. Then as the arm S is further elevated the tube D, which has so far remained stationary in relation to arm U, passes the center of gravity and moves the rest of the way by its own weight, its pin K moving in slot V. This simple lever, with moving fulcrum and weight, greatly economizes in operating-space, and serves to both lower and elevate the tube D.

\V is a coal-platform, which is built parallel with the railroad-track, and of a height about equal to that of tube D when the latter is lowered. Platform W is provided with a back, X, and this back and the platform are beveled, as at Y Z, at the ends, to obviate accident to the tube when it approaches the platform.

In the modification shown in Fig. 6 the front edges, a c, of the sides of tube D are beveled to an angle of about forty-five degrees, and the top E is likewise inclined downwardly and forwardly. This form of tube has its bottom piece longer than the top, and will readily take coal from a pile on an ordinary platform without the back X. l

The operation and advantages of my invention will be readily understood. is filled with coal, and as the train approaches, the tube D, which is normally elevated, is lowered by operating lever B. As thetrain passes, tube D scoops in the coal and conveys it to the tender, when the tube may be again elevated, the train being all the while in motion. It is a well-known fact and law of physics that when an object is traveling in a straight line, if its direction is changed to a right angle to the straight line, its momentum is destroyed and it falls by gravity. In this case the coal The platform is forced through the tube by the velocity of the train, and by reason of the elliptical quadrantal shape of the side I its angles of incidence are changed at every point in its passage through the tube until it reaches the point of a right angle to the opening. The momentum of the coal is then destroyed, and its acquired inertia with the train carries it forward until it falls by its gravity to the bottom of the tender. The force of the falling coal in this case will be less than when it is filled into the tender from a chute, as heretofore.

I claim as new 1. The method of taking coal on locomotivetenders while in motion, consisting in forcing the same by the velocity of the train into and IOC) through a tube that will change the angle of incidence at every point until a right angle to the former path of the coal is reached, when its momentum is destroyed and it falls by its own gravity into the tender, as set forth.

2. In a device for taking coal on locomotivetenders while in motion, a tube having an elliptical quadrantal guide-wall, I, as set forth.

3. The combination, with a locomotive-tender, of a hinged curved tube, D, adapted to take in coal while the tender is in motion, as set forth.

4. The combination, with a locomotive-tender having a fulcrum-standard, L, of a hinged curved tube for taking in the coal, and an operating-lever for lowering and elevating thctubc, as set forth.

5. The combination, with a hinged tube, D, having a pin, K, of a substantially T-shaped lever, B, having a slotted end, U, an operating end S, and a shank or stem, Q, working and sliding in a vertical fulcrum-standard, as set forth.

6. The combination of the tender having vertical bifurcated slotted standard L and longitudinally-slotted vertical guide 0, the hinged curved tube D, having pin 'K, and substantially T-shaped lever B, having slotted end U, operating end S, and stem Q, with pins T T, as set forth.

7. The combination of the platform parallel with the track, the hinged tube on the tender, having elliptical quadrantal wall I, and the operatinglever, as set forth.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.
